Medicament dispenser

A method of using a dispenser with a medicament bottle containing a medicament, the method comprising:

• attaching the dispenser to the medicament bottle by fixing an inner part of the dispenser to a neck portion of the medicament bottle, the dispenser comprising an outer part having a dose dispensing chamber, a circumferential wall, and an outlet in the circumferential wall, the inner part rotatably disposed within the outer part, the inner part having a dosing aperture, a circumferential wall, and an outlet in the circumferential wall of the inner part;
• setting the inner and outer parts of the dispenser in a dosing position in which the dosing aperture communicates with the dose dispensing chamber;
• inverting the medicament bottle so that the medicament collects in the neck portion of the medicament bottle above the dispenser with a single dose of medicament disposed in the dosing aperture;
• rotating the outer part relative to the inner part into a dispensing position in which the dose dispensing chamber, the outlet in the circumferential wall of the inner part, and the outlet in the circumferential wall of the outer part align to define a dose dispensing path, to cause the single dose to pass through the dosing aperture and into the dose dispensing chamber;
• and
• tilting the medicament bottle to cause the single dose to fall out of the dose dispensing chamber along the dose dispensing path.

A medicament container comprising:

• a medicament;
• and
• a dispenser attachable to the medicament container and configured to convey a dose of medicament out of the medicament container in use, the dispenser comprising:
• an outer part having a dose dispensing chamber, a circumferential wall, and a dose dispensing outlet in the circumferential wall;
• and
• an inner part rotatably disposed within the outer part, the inner part having a dosing aperture, a circumferential wall, and a dose dispensing outlet in the circumferential wall of the inner part;
• wherein the outer part is rotatable relative to the inner part between a dosing position, in which the dosing aperture communicates with the dose dispensing chamber to allow a dose to pass through the dosing aperture and into the dose dispensing chamber, and a dispensing position, in which the dose dispensing chamber, the dose dispensing outlet in the circumferential wall of the inner part, and the dose dispensing outlet in the circumferential wall of the outer part align to define a dose dispensing path out of the dispenser for delivery of the dose to a user.
